i looked all over ebay and i cant find any diecast newer version ('07-'10) of the chevy tahoe, chevy suburban, gmc acadia or gmc yukon denali anywhere!!! The only one i found was the tahoe and it was 1/24 scale, all the cars i have are 1/18. and is there even a very big difference? Any suggestions? these are like my favorite cars so any advice on where i can find any of these (within $10-$30) would be much appreciated!
